Nowadays, mobile phones have become an indispensable tool in people's hands. The key role of mobile phones is to make calls. The most important thing when making a call is the signal of the mobile phone. Many places, such as public places and homes, have WiFi wireless networks, which is an amplification of the signal function of mobile phones. There should be many people who know cell phone signal booster, but not many people know the working principle of cell phone signal booster, so you need to know some installation principles of cell phone signal booster. Next, we share the relevant content of the mobile phone signal enhancer, hope it will be helpful to everyone.

With the rapid development of mobile communication networks, network coverage continues to expand. Wireless communication relies on the propagation of electromagnetic waves to establish a communication link. With the continuous development of various buildings and traffic roads, it is blocked by buildings. In some large buildings, basements, shopping malls, restaurants, home improvement, entertainment venues and many other places, wireless communication has some weak links and cannot meet the needs of customers. The mobile phone signal is very weak and cannot be used normally.

At present, the main reasons for poor mobile phone signal are:

1) Blind area: After the signal is lost, the receiving sensitivity of the mobile phone is lower than that of the mobile phone, resulting in poor mobile phone communication;

2) Weak link: The main reason is that the receiving sensitivity of the mobile phone is lower than the receiving sensitivity of the mobile phone after the signal is lost, resulting in poor call quality of the mobile phone;

3) Conflict area: The wireless signals in the high-rise building area mainly come from multiple cells, most of which are unstable reflected signals on the ground and walls, which cause frequent switching (ie, ping-pong effect), which seriously affects the normal communication of mobile phones;

4) Busy area: Mainly in areas with high traffic, the capacity of the base station is difficult to meet the communication needs, and users cannot access the mobile network for normal communication.

The mobile signal amplifier (micro repeater, also known as the mobile signal booster) is specially designed to solve the above-mentioned weak links of the mobile signal. The product has the characteristics of small size, flexible installation, etc., and can cover indoor signals deeply. Practice has proved that it can provide stable and reliable signals for indoor mobile communication users, enabling users to enjoy high-quality personal communication services indoors.

1. How to install a mobile phone signal amplifier?

1. Selection: Choose different mobile phone signal repeaters according to different regions and building structures.

2. Antenna distribution: The directional octave antenna is used outdoors, and the antenna direction can point to the company's transmitting base station as much as possible to achieve the best reception effect. The omnidirectional antenna can be used indoors, and the installation height is 2-3m (the number and location of the antenna installation are related to the indoor area and indoor structure). Only one antenna is required to be installed in the unstoppable area of 300 square meters and below, two antennas are required to be installed in the range of 300-500 square meters, and three antennas are required to be installed in the range of 500-800 square meters.

3. Installation of mobile phone signal amplifier: generally installed at a distance of more than 2m from the ground. The installation location of the equipment and the distance between indoor and outdoor antennas should use the shortest path to achieve the best results.

4. Wire use: The signal amplifier standard is the communication industry, and the standard is 50Ω. If the impedance is incorrect, the system indicators will deteriorate. The thickness of the steel wire depends on the actual situation on site. The longer the line, the thicker the line to reduce signal attenuation.

5. Before the equipment is powered on, all indoor and outdoor antennas should be connected well to avoid damage to the equipment. Indoor and outdoor antennas should be installed on different planes as much as possible.

2. Precautions for the installation of signal amplifier

1. Select the model.

The mobile signal amplifier selects the model mainly according to the signal coverage area and the structure of the building. If the signal is too weak, the coverage will be incomplete, but if the signal is too strong, it will interfere with the outdoor signal.

2. Arrange the antenna.

The directional logarithmic antenna is used outdoors, and the antenna direction is aligned with the mobile company's transmitting base station as much as possible to achieve the best reception effect. The height of the indoor omnidirectional antenna is 2-3 meters. For indoor areas and barrier-free areas less than 300 square meters, only one antenna needs to be installed. For an indoor area of 300-500 square meters, two antennas need to be installed, and an indoor area of 500-800 square meters needs three antennas. When installing an indoor antenna, make sure that the outdoor antenna cannot receive the signal, otherwise it will cause self-excitation.

3. Install a mobile phone signal amplifier.

It is recommended that the cell phone signal amplifier be installed about 2m away from the ground. The shortest line should be the best distance between the mobile phone signal amplifier and indoor and outdoor antennas, because the longer the line, the weaker the signal.

The above is the sharing of our company, hoping to help you solve the problem of poor mobile phone signal.
